I will be rolling for initiative at the start of the battle, then I will be going by that order for the entire duration. Both the Immortals and Brootalz will receive significant amounts of reinforcements at the end of Turn 2. The Secret Faction will arrive at the end of turn 3.

The battle will end when either side's forces have been eliminated, or if the Brootalz completely break through the Immortal defenses. Stats of all the units will be DMed to all participants before the start of the battle, then orders can be sent.
